Answer:

3b − 2 = 4

Step-by-step explanation:

2b + 24 = 30

3b − 2 = 4

b + 4 = 8

2b − 3 = 0

2b + 24 = 30

2(2) + 24 = 30

4 + 24 = 30

28 ≠ 30

-----------------------------------------------------------------------------------------------------------------

3b − 2 = 4

3(2) - 2 = 4

6 - 2 = 4

4 = 4

-----------------------------------------------------------------------------------------------------------------

b + 4 = 8

(2) + 4 = 8

6 ≠ 8

-----------------------------------------------------------------------------------------------------------------

2b - 3 = 0

2(2) - 3 = 0

4 - 3 = 0

1 ≠ 0

Answer:

The probability that all 4 units are good is 10.66%.

Step-by-step explanation:

Given that a shipement of 14 microwave ovens contains six defective units, and a vending company has ordered 4 of these units and selection will be random, to determine what is the probability that all 4 units are good the following calculation must be performed:

14 - 6 = 8

8/14 x 8/14 x 8/14 x 8/14 = X

0.5714 x 0.5714 x 0.5714 x 0.5714 = X

0.1066 = X

0.1066 x 100 = 10.66

Therefore, the probability that all 4 units are good is 10.66%.
